AI Technical Summary
Technical Problem
Existing diaphragm wall construction techniques are not suitable for continuous interlocking holes drilled in hard rock strata, leading to construction difficulties.
Method used
The underground continuous wall structure adopts a beaded type, which includes a steel cage in the concrete wall, continuously interlocking arc piles on the outside and diaphragms and arc protrusions on the inside. It adapts to the pores in hard rock strata through geometric interlocking effect, thereby enhancing the embedment force and shear resistance.
Benefits of technology
It enables precise construction in hard rock formations, enhances the embedding force between the wall and the hard rock, blocks the seepage path of groundwater, and improves shear resistance and service life.

Abstract
A kind of bead type underground continuous wall structure, the concrete wall is provided with reinforcement cage, the outer side of the concrete wall is provided with several arc piles that are continuously engaged, the inner side of the concrete wall is provided with a partition, and the partition is provided with arc protrusions arranged corresponding to the arc piles.The engagement design of the arc piles not only enhances the embedded force of the wall and hard rock, but also improves the shear resistance through geometric optimization, ensuring the stability of the wall under complex geological conditions.The arc protrusions on the side of the partition and the outer arc piles form a "double-arc engagement" structure, which can further adapt to the continuous holes drilled in hard rock strata and block the groundwater seepage path through the geometric interlocking effect, eliminating the gap between the traditional wall and the internal structure, preventing the intrusion of corrosive media and prolonging the service life.The invention breaks through the limitations of traditional underground continuous walls on geological conditions.
